Purpose: The aim of our study is to evaluate the factors affecting surgical margin positivity among patients with invasive ductal breast cancer who underwent breast-conserving surgery (BCS) after preoperative diagnostic core biopsy. Methods: Two hundred sixteen patients with stage I, II invasive ductal breast carcinoma who had histological diagnosis with preoperative tru-cut biopsy and underwent BCS were included in the present study. Potential factors that affect the positive surgical margin were analyzed. In univariate analysis, the comparisons of the factors affecting the surgical margin positivity were made by chi-square test. Logistic regression test was used to detect the independent factors affecting the surgical margin positivity. Results: Positive axillary lymph node (odds ratio [OR], 8.2; 95% confidence interval [CI], 3.01 to 22.12), lymphovascular invasion (LVI; OR, 3.9; 95% CI, 1.62 to 9.24), extensive intraductal component (EIC; OR, 6.1; 95% CI, 2.30 to 16.00), presence of spiculation (OR, 5.1; 95% CI, 2.00 to 13.10) or presence of microcalcification in the mammography (OR, 13.7; 95% CI, 4.04 to 46.71) have been found to be the independent and adverse factors affecting surgical margin positivity. Conclusion: Considering decision making for the extent of the excision and for achieving negative surgical margin before BCS, positive axillary lymph node, LVI, EIC, spiculation or microcalcification in mammography are related as predictor factors for positive surgical margin.
